[[WMG: Danny is a Troper today.]]
Think about it. At the age of nine, he's already GenreSavvy enough to [[LampshadeHanging hang up proverbial lampshades]] by the dozen. Then he goes through an adventure that's more {{Troperiffic}} than any movie he has seen so far which is impressive considering how {{Troperiffic}} the ''[[ShowWithinAShow Jack Slater]]'' movies have already been until then. Now imagine him today, some 30 years old, and most likely a movie addict.
* Nine. The kid is eleven at youngest. Watch the way he acts around Meredith/Whitney. This kid is obviously already in at least the start of puberty.

[[WMG: The "real world" of Last Action Hero also has some of Arnold Schwarzenegger's roles being played by other actors]]
Last Action Hero establishes that there have been 4 Jack Slater movies, which probably means that at least 4 movies that Arnold made in our world would have other actors in his roles due to his commitments to Jack Slater leaving him unable to take those roles.

[[WMG: The Last Action Hero doesn't parody only action films...]]
The scenes set in the "real world" are actually a clever satire of Film Noir. Consider- it's almost always night and it constantly rains. The movie theater is falling apart and appears to have its doors ripped from some Gothic keep. Criminals are able to kill openly in the streets and the police never arrive. The villain manages to outwit the hero and shoot him in their final confrontation. No one even cares that Death himself walks the streets, because Danny has simply jumped from one genre pastiche to another!
* Well, the ones who saw him come out of the screen were rather scared. Everybody else probably just assumed he was some guy in a costume. On the other hand, one has to ask what difference Death's being personified in any world would make whether anyone noticed him or not. Wouldn't he just go on plying his trade the same as before, which was pretty much what he did in this movie?

[[WMG: Related to the previous theory: there is no "realest" world at all.]]
Slater believes his world is real. So does Danny. It's possible that both universes are MutuallyFictional, with Slater living in an action movie universe and Danny in a film noir universe. There is no universe that's "more real" than the others -- they simply work by different laws of fiction.
* What does that make Earth Prime (our universe)?
** A place with an [[{{God}} Author]] with enough of a sense of irony/humor to build a world that could contain all genres of stories, some real and some fictional.
*** But the Jack Slater movies were created by someone in Danny's universe, so does that mean [[ParanoiaFuel OUR universe is fictional as well?]]

[[WMG: Benedict's plan to bring together all the villains would have failed.]]
Why? Who the hell is this guy to them? Why would any of them follow that guy? Why would they believe him? How could he keep them under control? And why wouldn't some of them just eat him?
* Considering how frighteningly quickly Benedict figured out the rules of the real world, including how to manipulate them to his advantage, I feel comfortable assuming that before he collected these guys he'd have figured out a means of control. Even King Kong is manageable if you remember to stop by any place that has giant mecha.
* This troper gets the impression that he can control them as long as he holds the ticket.
** This is never stated, it only allows transport from movie worlds.
* Another reason it might fail is because of YourMagicsNoGoodHere, Jack is shown to not be able to do most of the things he can do in his movie's world, he can't walk off bullet wounds or a smash a car window barehanded, while Death is shown maybe killing someone, it could just be that he knew the person was going to die, Benedict could summon all of those horror creatures but they would just be freakishly looking creatures here with no power.

[[WMG: Creator/TomNoonan gets arrested for murdering his agent.]]
He shows up in full Ripper regalia, acting all killer-y. Then, his agent is found dead from an axe wound. Any witness would say, "last time I saw him, he was walking to a secluded area with Tom." Mr. Noonan is royally screwed. He does have hope, though. He was seen showing up at the premier a few minutes later as himself (I think even with his wife). This would lend plenty of credence to an argument that the Ripper was some sick imposter. Hell, eventually someone's going to check up on the downed power lines on the roof and find the Ripper's body. How the world will react when it becomes known that this deranged lunatic has the same finger prints, dental records, and DNA as famed character actor Tom Noonan is not known. To put it simply, Tom's got some bad times ahead.
** The Ripper's corpse would have been found up on the roof, presumably, which then goes on to create a real headscratcher for the world as to how this guy is identical to Tom Noonan in every way.
*** Also, assuming the timeframe of the real world in the film is 1993 and Tom Noonan himself isn't seen at the premiere, he was probably on the set filming an independent film called ''What Happened Was...'', which he starred, written, directed, edited and composed (based on a stage play of his). So, he may not have even been in New York at the time of the filming if it's the same.

[[WMG: Jack Slater is a NoCelebritiesWereHarmed version of [[WesternAnimation/TheSimpsons McBain]].]]
Let's face it, this is the closest we'll ever see to a real [=McBain=] movie.
** [[WesternAnimation/TheSimpsons Yeah, I'll say. Magic ticket my ass, [=McBain=].]]

[[WMG: The action sequences that Danny gets dropped into actually do happen in ''Jack Slater IV'']]
Obviously, the action sequences and the various parts of the setpieces had to have unfolded in the actual movie the way we see them when Danny gets dropped in, but perhaps altered as they'd unfold differently without Danny's presence: for instance, the scene where Benedict and his henchmen interrogate Danny at Slater's daughter's house probably happens in ''Jack Slater IV'', but Benedict is coming to interrogate Slater himself. So Benedict's Sherlock Holmes remark and question about how Danny knows him probably asked albeit in a different form.

The same rule of logic also applies to both the car chase at the start of ''Jack Slater IV'' and the rooftop funeral later in the movie.

[[WMG: The death of Jack's son destroyed his marriage.]]
They were no doubt married prior to that event but the death of his son was what caused Jack's life to go into a downward spiral; his wife resents him because his lifestyle was what cost them the life of their son. And no doubt robbed their daughter a chance to have a normal childhood. She couldn't bare to look at the same guy she felt was just as responsible for their son dying as The Ripper was. So she broke off the marriage and start a new life without Jack.

[[WMG: Danny grew up to be Jay of The View Askewniverse]]
And continues to get into wacky adventures but this time he has a friend in Silent Bob to join him.
* As funny as it is, it's jossed for the fact that ''Jay and Silent Bob Strike Back'' features a scene that takes place in 1970s that shows how Jay and Silent Bob met.

[[WMG: At some point in the near future, this will be rebooted.]]
And, knowing Hollywood, they'll cast Wrestling/DwayneJohnson as Jack.
* Both in and out-of-universe.

[[WMG: Benedict is Tywin Lannister from the TV series ''Series/GameOfThrones''.]]
Benedict wasn't killed by the explosion but transported to Westeros, where his ability to quickly learn and adapt to the rules of fictional and non-fictional worlds and ruthless personality allowed him to rise in power to become the ruthless feudal lord Tywin Lannister.
This is supported by:
* Danny was saved from an explosion that should have killed him by the ticket transporting him to another world, why wouldn't it do the same for Benedict?
* If Benedict replaced Tywin in the tv series version of Westeros this would explain why he looks so different from the version of Tywin from ''The Song of Ice and Fire'' novels.
This is contradicted by:
* Tywin was famous enough that an extremely popular song was written about something he did as a teenager (The Rains of Castamere), and had children long before he was as old as Benedict is in this film. They would surely recognize that he was replaced by someone else, especially since...
* He would not know the language spoken around him, as the text is translated to English and is not supposed to represent literally what is being said.

[[WMG: Whitney would have been Jack's sidekick in ''Jack Slater IV'' if Danny hadn't showed up.]]
If Danny hadn't ended up in the film, Jack's daughter Whitney would have been Jack's sidekick for the film. This would explain why Whitney was featured in the promotional standee (if she was a one-scene wonder, she wouldn't have been featured in any promotional material). The whole setup with kissing the French student makes sense in a comedic stance, so she would have still applied to the "comedic sidekick" trope that Danny recognizes himself as while also being the bad-ass sidekick as well.

[[WMG: Jack Slater's son, as well as anyone else killed in the movie, can be brought BackFromTheDead by FanFics.]]
* Alternatively, someone writes a FixFic where Jack manages to grab his son's hand in time and shoots the Ripper in the face so he would let go (assuming the Ripper was still clinging onto Andy when father and son see each other for the last time).

[[WMG: Danny's father was a cop.]]
* That's why his mom was so blase about Jack being one.
** Maybe this also explains the title of the film. We know that Jack is the titular ''Last Action Hero''. Maybe in Danny's eyes, Danny's father was his First Action Hero.
** It's explicitly said that Danny's mom is a widower, so the cop theory has a very good chance of being true.

[[WMG: Danny grows up to be a film writer/director and does a rendering of his experience as a feature film.]]
Danny's living experience really sucks, which explains why he's so into watching action movies. Considering he's such an action film fan, he eventually grows up to expand his palette to other films and eventually goes to film school. He eventually starts his film career and he does a rendering of his adventure with Jack as a SerialNumbersFiledOff version of the events. It isn't well received because it goes up against a film from a high profile director and ends up becoming a cult classic.

[[WMG:Danny disappears after the ending of the movie]]
There is no way he's staying in the real world after getting his ticket. The one thing that his character development doesn't cover is moving on from his constant escapism. He's probably going to leave his mom a letter inventing some excuse and then disappear into movie land for the next few decades. Maybe the plot of the sequel would involve him returning to the real world in the 2020s and realizing how terrible and unoriginal movies have become since his time.
